Re: Perforce problem with XCode 3.1.1

Many thanks to the XCode list member who answered me off-list. The problem was that my project root was set to the default location, which is the same directory as the project file. This apparently prevents the SCM system from looking elsewhere, even though the project file contains files from other directories.

The "solution" is to move the project root up one level, to the common folder that encloses both the project folder and the common headers.

I still believe that this behavior is broken (although I can't find any documentation on what the "Root" of the XCode project is supposed to be...). XCode's SCM system should be smart enough to get the Perforce information for the files incorporated in the project, no matter where they are. It should also be smart enough not to get SCM information for hundreds of files that are not in my project, which it does now that I've moved the root.

As well, there is absolutely no error indication when you try to "Edit" files that XCode is not able to get SCM information on. A simple message like "This file is outside of the project root directory, so SCM information is unavailable" would have saved me a couple of hours of puzzlement.

Now that I've been clued into the solution, I also see that this is apparently a problem that was introduced in XCode 3.0. I'm sorry to see that it's still a problem a full year after this thread reported it:

Greetings,

I'm having a bit of a problem with the Perforce SCM integration with XCode 3.1.1, and I wonder if anybody knows what the trouble might be.

I have an XCode project file in 2.4-compatible format. It has about 43 files in the Groups & Files list, some of which are at the top level, and some of which are in groups.

I have configured a repository for my company's Perforce server, and the status indicator shows green. I have set the project's repository to that Perforce repository.

Here's the problem: XCode only seems to get SCM information for about half of the files. If I open the SCM Results window, the file listing at the top shows 21 files, but omits the rest.

The only pattern I can detect here is that the files that don't show up for SCM reside in a different directory from the project file. This is because my project shares a set of common headers with a second project, so the common headers are in a folder outside the folder that contains my project file:



Perforce root folder
   Project folder 1
       MyProject.xcodeproj
       <files that show up with SCM information>
   Project folder 2
       <stuff that I'm not working on right now>
   Common Headers
       <files that are included by reference in
        MyProject.xcodeproj, but that don't work
        with SCM within that project>


Or, if this will wrap properly:


Perforce root folder | _____________________________|_____________________ | | | Project Folder 1 Common Headers Project folder 2 | | Working files live here Non-working files live here MyProject.xcodeproj


All of the affected files are set up with "project relative" paths, and are openable, editable and buildable within XCode, as well as being integrated into the CodeSense index. They are all within the folder hierarchy managed by the Perforce workspace.


Is this just a bug in the SCM handling, with it refusing to look outside the project's folder?

Thanks,
--Mike
